I definitely agree with DDLM and epo: Dawn can't be blamed for those breakups! Buffy and Riley were not working out at all, and Dawn just made a small comment to Riley and he blew it out of proportion.I liked Dawn in the last season but besides that no. If you think about she helped split up 3 relationships Buffy/riley, Willow/Tara and Xander/Anya. Buffy/Riley by telling Riley buffy didn't get worked up over him like she did with angel. Willow/Tara by telling Tara about the fight in OMWF. Xander/Anya by telling Anya Xander went missing.
Tara would have eventually figured out that Willow was messing with her head, and she needed to know. Dawn just (once again) made an innocent comment.
And even if Anya hadn't of overheard Dawn saying that Xander left, I'm sure Anya would have figured it out eventually that he was gone. Dawn didn't make Xander leave or anything.
